I looked at this 28 last week. The interior looked nearly new -- pristine. In my opinion it would still need: New standing and running rigging, bottom job, new sails, exterior bright work, and mast re-anodizing.) Owner was a great guy as well. He's owned it since 1989.
Gently used Ericson 28' sailing sloop (designed by Bruce King) with classic features of a traditional Ericson sail boat. A solid, responsive, fast boat. Easy to sail! Only 2 owners - we have owned...

That 28 looks like a fairly clean specimen to me. And I don't find the cushions objectionable, personally.
The layout of my 26 is very much like a shrunk-down version of the 28. One thing I'd point out about this design is that the quarter berth is not especially useful as a sleeping berth. On my 26 (which may or may not be true of the 28), the starboard settee pulls out into a double. It makes a very wide and comfortable berth. But that means it would be the berth of choice, and anytime someone would want to use the quarter berth the settee would already be in use. Getting in and out of the QB involves some contortions even when the settee is clear, but getting in and out with someone laying down in the settee would entail stepping over (on?) whomever is in it. On my 26 the QB serves as a much-needed "garage," where I store the dinghy, cockpit cushions, and various other stuff, so I wouldn't use it for sleeping in any case. I've never seen the ergonomics of it on the 28 in person, though, but I'm guessing you might find the same to be true.
On my 26, the port berth is too narrow for sleeping comfortably, but the extra beam of the 28 might translate into a more useful berth. It's something you might want to check. (I have plans, by the way, to make a collapsible extension for the port berth so I can widen it about 6" for when I need to sleep someone in it.)
On my 26, the vee berth is comfortable once you contort your way into it, which take some effort due to the low headroom. The extra size on the 28 might translate into a taller vee-berth and obviate that issue. Again, something else to check out.
